Rockler Amps Up iPhone Music with New Koostik Kit

Wooden Cradle Amplifies iPhone Music Without Plugging In

MEDINA, MN (October 8, 2013) - Rockler Woodworking and Hardware has introduced the Koostik Kit, a free-standing wooden cradle that fits any model iPhone and uses passive amplification to boost the iPhone's sound to a higher volume. The cradle is made of intricately shaped cherry wood, which creates acoustic properties that amplify the sound volume by two to four times without using any electrical power beyond that of the iPhone. iPhone users can simply cue up a playlist, set the phone in the Koostik cradle, and instantly enjoy the amplified sound throughout the room.


"When the iPhone is placed in the Koostik cradle, the music is instantly amplified due to the carefully designed sound channels and acoustic chambers. The sound will fill the room without using any additional power beyond what the iPhone uses to operate," says Scott Ekman, Rockler's Vice President of Marketing. "We think do-it-yourselfers will enjoy building the Koostik to give as a gift or to keep for themselves."


The Koostik Kit contains two rectangular pieces of unfinished, solid cherry wood – the faceplate and the cradle – and allows users to determine the final shape by beveling the edges if desired and choosing a custom finish to apply to the exterior. The Koostik is easily assembled by gluing the faceplate to the cradle, and detailed instructions are included. The pre-machined cradle slot fits all versions of the iPhone.


The Koostik Kit (45631) retails for $49.99 and can be purchased at Rockler Woodworking and Hardware stores nationwide, Rockler independent resellers,, or from the Rockler catalog.
